Y 2 Claims (01. -48) Thisinvention relates to an adjustable chair or the like and while it can be used in connection with various types of furniture, it is designed primarily for use with. a chair intended ing means being employed for maintaining the,

extensions in operative position when the legs are elongated. i

A further object is to provide a structure of thischaracter which is simple. durable and efiicient and whichdoes not detract materially from the appearance of the article of furniture.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction, and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangementof parts without departing from the spirit of the invention as claimed. i

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing:

. Figure l'is a sideelevation 'of a chair equipped with the present improvement, the leg extensions being folded out of the way. i Figure 2 is an enlarged side elevation show ing the extensions positioned to hold the seat of the chair at a higher elevation.

Figure 3 is a section on'line 33, Figure 2.

Figure 4 is a section on line l -4, Figure 2.

Referring to the figures by characters of reference'l designates a pair of leaf hinges adapted to be secured by screws 2 or'the like to one pair of legs L. Movable leaves 3 are hingedly connectedto the leaves I as shown at 4 and to each of these movable leaves is secured a leg extension 5 of any desired length and so shapedas to fit snugly against the lower ends.

' of the legs L when-the extensions are projected into active positions as shown inFigure 1. Each of the leaves 3 is provided at one side withan ear 6 and the ears of the pair of leaves are connected by links I pivotally joined as at 8. One of these links is extended'well beyond the pivotal connection 8, asshown at 9 and is adapted to move downwardly against a stop projection HI pressed from the other link 1 into the path of the end portion 9. When the parts are thus located the two links will bein alinement and the leg extensions 5 will be pressed snugly against the lower ends of the legs L so as to aline therewith as shown in Figure Consequently seat S of the chair C will be supported at a higher level than should the lower ends of legs L be in contact with the floor "or other supporting surface as in Figure 1.

When it is not desired to use the extensions 5 for the purpose of supporting the chair seat at a higher level than ordinarily, the point of connection a between the? links I is pressed upwardly, thus breaking the joint between the danger of them falling out of place.

- It is to be understood bf course that one of these devices is to be mounted between. the legs links. .One of the extensions 5 is then swung at each side of the chairor the like or, if pre ferredpone can be located between the front legs and another can be located betweenthe back legs. Under all conditions, however, the adjustment and foldingisyefiected in the same manneras heretofore described.

What is claimed is:

1. The combination with anarticle of furniture having a pair of legs, of extension devices hingedly connected to the respective legs and movable relative thereto into position either in alinement with and abutting against the lower ends .off theglegs or in upwardly extended position above said lower ends and between the'legs, and means connecting the extensions for hold ing them in either of said positions,said means including pivotally connected links pivotally.

joined to the respective, extensions,-and means for limiting the relative swinging movement of the links inone direction.

-2. The combination with an article of furniture having a pairof legs, of an extension attachmeri't therefor including hinges secured to the respective legs, extension members connected by the hinges to thelegs and movable into position below and in alinement with the legs or above the bottoms of the legs and between said legs, links pivotally connected. to the respective extension members, a pivotal connection between the links, and cooperating means :on the, links? for holding them againstrelativel swinging movement in one direction, said links a cooperating to hold the extension members in either of their respective positions.
